摘要：
A simultaneous bidirectional port coupled to a bus combines a synchronization circuit and a data transceiver circuit. The combination data and synchronization transceiver circuit synchronizes the port with another simultaneous data port coupled to the same bus. The combination data and synchronization transceiver circuit includes a driver with a variable output impedance. Prior to synchronization, the driver has an imbalanced output impedance, and after synchronization, the driver has a substantially balanced output impedance.
